SOLE-LEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 546,211, datedSeptember 10, 1895.

Original application filed March 8, 1393, Serial No. 465,176. 507,760i.

To all whom it may concern:

Be it known that we, ERASTUS E. \VINKLEY and BENJAMIN PHILLIPS, citizensof the United States, and residents of Lynn, in the county of Essex andCommonwealth of Massachusetts, have invented a new and usefulImprovement in SoleLeveling Machines, of which the following is aspecification.

Our invention relates to improvements in ID that class of sole-levelingmachines by which the operation of leveling is performed by avibratingleveling-roll applied under pressure to the sole of a shoe; andit consists of the method of mounting the roll and changing its lateralinclination and of the devices and combination of devices hereinafterset forth and claimed, this application being a division of our pendingapplication, filed March. 8, 1893, Serial No. 465,176, for improvementsin leveling-machines, and embracing one of the alternate constructionsshown and described but not specifically claimed therein.

The object of our invention is to increase the efficiency and capacityof this class of leveling-machines.

Our invention is illustrated by the drawings herewith submitted, inwhich- Fignre l is a side view of a machine em bodying our invention.Fig. 2 is a plan view 0 of same. Fig. 3 is a sectional view on line X X,Fig. 1. Figs. 4 and 5 are respectively a face and reverse plan view ofwheel forming part of said machine, showing face-cam and a portion ofperiphery-cam on same. Fig. 6

- 5 is a side view of roll-carrier and roll-carrier bed; Fig.7 is alongitudinal section through same. Fig. 8 is a section on line Y Y, Fig.6.

Similar letters and figures refer to similar parts throughout theseveral views.

Referring to the drawings, R represents the leveling-roll, shown asconcave, but the form of which may be varied. To the levelingroll R weimpart vibrating motion by the following mechanism: Mounted in frame A,4 5 which is a frame suitable to support the working parts of themachine, is a shaft .13, to which power may be applied by any convenientdevice. The shaft B carries a roll 1, in which is cut the cam-path 2. Inthe cam-path 5o 2 runs the cam-roll 3, carried by the pivoted Dividedand this application filed April 16, 1394. Serial No. (No model.)

lever 4, at or near its lower end, the lever 4 being intermediatelypivoted to a suitable support on the frame A and pivoted at or near itsupper end to a connectingrod 5, which is pivotally connected with therollcarrier bed 6. The roll-carrier bed 6 is free to slide in suitableways in the frame A, and upon it is mounted the roll-carrier 26, theouter end of which is forked and provided with hearings, in which ismounted the leveling-roll R.

Our method of mounting the roll R consists in providing the same withbearings which are vertically adjustable and laterally rocking andcontrolled in both of such movemerits by suitably-placed springs.

As above stated, the bearings for roll R are placed at the outer end ofthe roll-carrier 2G, and to render the same vertically adjustable therollcarrier 26 is pivoted at or near its inner end to the roll'carrierbed 6, leaving the outer end carrying. the bearing of roll R free to beraised or lowered. The outer end of roll-carrier 26 extends beyond thecarrier-bed 6 and is curved downward to bring rollR into convenientposition to operate, as hereinafter described. The roll-carrier 26normally rests on the roll-carrier bed 6, and the upward niovement ofits outer end, carrying roll R, is controlled by the springs 27 27,mounted on the bed 6, near its outer end, and connected by a cross-head28, through which runs a threaded bolt 29, which bears against. theroll-carrier 26, so that the same is raised againstthe tensions ofsprings 27 :27, which may be regulated by means of the bolt 29, which isprovided with a suitable hand-wheel for the purpose.

The bearings of roll R are rendered later ally rocking by the followingdevice: The rollcarrier 26 consists of two parts a and c, of which thepart a carries the roll B, and the part c is pivoted to the bed 6. Tothe part 0: is secured a cylindrical tongue I), which ex tends through asleeve 6 on the part c, in which it is free to rotate, but is prevented5 from sliding by suitable stops. By such arrangement the part a isallowed a rocking movement, which is controlled by the springs 30 30,bearing upon the part c, and suitable lugs h h, secured to the part a.

By the above-described method of mounting the roll we obtain andregulate pressure and render the rollcapable of adjusting itself to thecontour of either side or themiddle of the bottom of the last, leavingfor the mechanism hereinafter described the function of transferring itfrom one of such positions to the other.

The last-supportingjack is shown at E, but

forms no essential feature of our invention.

In theform shown in the drawings, Fig. 1, it is .provided with standardsfor supporting the last, adjustable vertically by means of setscrews 3131, and horizontal for different sizes of last by set-screw 32.

We find it convenient to oscillate the jack by the following-describedmechanism; but we do not wish to limit our invention to suchconstruction, and we would further say that by the term oscillating wewish to be understood as including a to-and-fro motion generally,whether alongarectilinear orcurvilinear path.

The shaft B carries a sleeve 7, on which is out a worm 8. The sleeve 7is free to rotate about the shaft B, but is prevented by suitable stopsfrom sliding on the same. By a clutch mechanism, hereinafter described,the sleeve 7 may be made to rotate with the shaft 13. In the frame A,above and transversely to the shaft B, is mounted ashaft C, which carries keyed or otherwise rigidly secured thereto a worm-gear 9, whichengages with the worm 8 on the shaft 13. Upon the shaft 0, also rigidlysecured thereto,isa wheel D, having on its face the path-cam 10, theform and function of which will be hereinafter more fully set forth. Inthe path-cam 10 runs the camroll 12, carried by the rod 13, the rear endof which is forked and embraces the shaft 0 and the front end pivoted tothe connectingrod 14, which is also pivotally connected with the arm 24,its connection therewith being rendered vertically adjustable by thecircular slot 33. At or near its front end the rod 13 is supported inbearings in standard 15. The arm 24 supports the jack E,,which issuitably mounted thereon. The arm 24 is mounted upon suitable bearingsin the frame A, upon which it is free to swing.

Torender the roll R automatically laterally rocking further than by themethod of mounting already described, we find the following to be aconvenient mechanism: Upon thesvheel D is the periphery path-cam 11,theparticular form and function of which will be hereinafter more fullydescribed, in which runs the cam-roll 17, carried at or near the rearend of the lever 18. The front end of the lever 18 is connected with thecross-head 19, j

which is mounted in suitable Ways 0 0 in the frame A, in which it isfree to slide, the connection between the cross-head 19 and the lever 18being arranged to allow play for swinging motion of lever 18. The lever18 is intermediately pivoted on frame A. The cross-head 19 is providedwith a slot 35, into which extends the rigid arm 36, secured to andadapted to rock the'roll-carrier bed 6. The sides of the slot may beconveniently curved to allow play for the swinging motion of the arm 36.

The sides of the carrierbed 6 are curved, and the ways it n in which itslides are also curved, and its connection p with rod 5 is swiveled orotherwise suitably arranged so that the carrier-bed may be vibratedwithout interfering with its rocking motion.

The clutch mechanism on shaft B is described as follows: A sleeve 37 issplined to shaft 15 and free to slide thereon. The sleeve 37 is notchedto engage with notches on sleeve 7 and normally held in engagementtherewith by a spring 38, bearing against a collar on said shaft B. Inthe sleeve 37 is an annular groove, in which runs a fork on the arm 39,which is free to rotate on rod 40, but prevented from sliding thereon bysuitable collars. The rod isfree to rotate and slide in suitablebearings in frame A and is provided with an operating-lever 41. Upon therod 40 is a rigid projection 42. On the wheel D is a dog 43, which uponrevolution of wheel D comes in contact with the rigid projection 42,pushes out rod 40, and by arm 39 and its fork running in groove insleeve 37 disengages sleeve 37 and 7. By rotating rod 40 projection 42maybe turned out of the way of the dog 43 and sleeve 37 thrown intoengagement with sleeve 7 by spring 38. The rod 40 may be also drawn outat any time by lever 41 and sleeves 37 and 7 disengaged.

The machine may be adapted for different sizes of shoes by raising orlowering the rod 14 in the slot 33, a suitable device 90 being providedwhereby the rod 14 may be secured in any desired position along the slot33.

In regard to the form of path-cams 10 and 11, it is sufficient to saythat they are so formed and timed with reference to each other that inco-operation with the bearings of roll R they present all essentialparts of the sole to the roll in such manner that the same is shapedthereby to conform to the contour of the last under the same.

It is evident from the foregoing that the method of mounting the roll Rhereinbefore described in constructions where cams 10 and 11 are usedsimplifies the form of such cams, and also that earns 10 and 11 may beso formed and timed with reference to each other and the jack E somounted that such mounting of the roll will be unnecessary, and,further, that our method of mounting the roll B. may be used inconstructions where cams l0 and 11 are omitted and another devicesubstituted for presenting the shoe to roll, all without varying theessential nature of our invention.

The operation of our machine is as follows: The machine being inadjustment to receive the size of shoe to be leveled and the power beingapplied thereto, the operator places a shoe upon the jack E and adjuststhe same vertically, as hereinbefore described. The 1e IIO ver 41 isthen pushed out and the wheel D begins to revolve. The shoe is therebycarried under the vibrating roll R and moves to and fro, while theleveling-roll vibrates over the same under pressure of springs 27 27,varying its inclination and length of operation on the different partsuntil the Wheel D has made a complete revolution, when the clutchmechanism is thrown out and the operation ceases, the shoe being thenthrown outin convenient position for removal by the operator.

lVe do not consider our invention limited to mechanism herein shown anddescribed; but

\Ve claim as novel and desire to secure by Letters Patent 1. In soleleveling machine, the combination with a vibrating leveling roll and ashoe supporting jack, of connected mechanism op-' erating automaticallyto change the relative lateral inclination and longitudinal position ofthe roll and jack, and means for adjusting said mechanism to regulatethe extent of the change in the relative longitudinal position of theroll and jack effected thereby, substantially as described.
